Abstract

The present invention relates to a technology for a sensor network, machine to machine (M2M) communication, machine type communication (MTC), and the Internet of things (IoT). The present invention may be utilized for an intelligent service (smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related service, etc.) on the basis of the technology. The present invention relates to a communication method and apparatus for a wearable device in a wireless communication system. The communication method of the present invention comprises the steps of: linking the wearable device to a user terminal located in a short range within which communication with the wearable device is possible, in order to communicate with the user terminal; and when the wearable device is operating in a power-saving mode, receiving, through the user terminal, data of the wearable device, which is transmitted on the basis of coupling information between the user terminal and the wearable device in a network.

Claims

1. A method for performing communication by a user terminal in a communication system, the method comprising:

interworking with a wearable device to communicate with the wearable device located within a short range which allows communication;

determining whether data of the wearable device is forwarded to the wearable device, on the basis of a type of the data of the wearable device, and

delivering the data of the wearable device which is received based on coupling information between the user terminal and the wearable device in a network, when it is determined that the data of the wearable device is forwarded to the wearable device.

2. The method of claim 1, further comprising registering the coupling information between the wearable device and the user terminal,

wherein the coupling information comprises mapping information between the wearable device and the user terminal.

3. The method of claim 1, wherein the determining of whether the data of the wearable device is forwarded to the wearable device, on the basis of a type of the data of the wearable device comprises, when the wearable device is operating in a power-saving mode (PSM), determining whether the data of the wearable device is forwarded to the wearable device, on the basis of the type of the data of the wearable device, a communication type used to interwork with the wearable device, and a state of the wearable device.

4. The method of claim 1, further comprising requesting for a direct connection of the wearable device to an application server, when it is determined that the data of the wearable device is not forwarded to the wearable device.

5. The method of claim 1, wherein the interworking with a wearable device is cancelled, when a PSM timer expires.

6. A user terminal of a communication system, the user terminal comprising:

a transceiver configured to perform data communication; and

a controller configured to;

interwork with a wearable device to communicate with the wearable device located within a short range which allows communication,

determine whether data of the wearable device is forwarded to the wearable device, on the basis of a type of the data of the wearable device, and

deliver the data of the wearable device which is received based on coupling information between the user terminal and the wearable device in a network, when it is determined that the data of the wearable device is forwarded to the wearable device.

7. The user terminal of claim 6,

wherein the controller is further configured to register the coupling information between the wearable device and the user terminal, and

wherein the coupling information comprises mapping information between the wearable device and the user terminal.

8. The user terminal of claim 6, wherein the controller is further configured to determine whether the data of the wearable device is forwarded to the wearable device, on the basis of the type of the data of the wearable device, a communication type used to interwork with the wearable device, and a state of the wearable device, when the wearable device is operating in a power-saving mode (PSM).

9. The user terminal of claim 6, wherein the controller is further configured to request for a direct connection of the wearable device to an application server, when it is determined that the data of the wearable device is not forwarded to the wearable device.

10. The user terminal of claim 6, wherein the controller is further configured to cancel interworking with the wearable device, when a PSM timer expires.

11. A method for performing communication by an application server in a communication system, the method comprising:

registering coupling information between a user terminal and a wearable device;

determining whether data of the wearable device is forwarded to the wearable device, on the basis of a type of the data of the wearable device; and

transmitting data to be transmitted to the wearable device to the user terminal on the basis of the registered coupling information, when it is determined that the data of the wearable device is forwarded to the wearable device.

12. The method of claim 11, further comprising:

directly transmitting the data of the wearable device to the wearable device, when it is determined that the data of the wearable device is not forwarded to the wearable device.

13. The method of claim 11, further comprising:

waiting for transmission of the data to be transmitted to the wearable device until a PSM timer is cancelled.
